How to break a bad habit

We all have habits we'd like to break, but the brain doesn't make changes easily. Breaking an unhealthy habit can be done; to do so, it helps to understand what's happening in the brain, know why you want to change, and accept that there will be setbacks along the way.

Study links common virus to MS

A 2022 Harvard study suggests that an Epstein-Barr virus infection, the most common cause of mononucleosis, may trigger multiple sclerosis (MS) in some people.

A common virus may be one contributing cause of multiple sclerosis

The vast majority of diseases do not have a single cause; rather, multiple factors combine to cause a disease. Growing evidence suggests that several viruses may be triggers of multiple sclerosis, and a long-term study found evidence that an infection with a common virus can be an important contributing factor in MS.

Can ALS be caused by traumatic brain injury?

Sleeping six hours or less is associated with impaired cognition, mostly in memory, as well as an increase in the protein that can form brain plaque. Sleeping nine hours or more is also linked to cognitive problems, especially in decision making.

Exposure to traffic noise linked to higher dementia risk

A decade or more of high exposure to traffic noise may increase dementia risk.

Working out your brain

Cardio exercise has been convincingly linked to less cognitive decline and may even improve cognitive functioning. Research suggests it can strengthen the heart, promote arterial health, improve blood flow to the brain, fight inflammation, and increase key chemicals that promote new brain cell growth. The type of exercise does not matter, but cardio that is both physically challenging and offers mental stimulation is ideal.

Too much coffee may raise dementia risk

Drinking coffee daily can provide a welcomed mental jolt for many people. But new research suggests regular coffee drinkers should stop at five or six cups per day, as drinking more may increase their risk for dementia.

Can friends who listen help protect your memory and thinking skills?

A study published online Aug. 16, 2021, by JAMA Network Open suggests that older adults with good listeners in their lives have better thinking skills—despite decreases in brain volume—compared with people who don’t have good listeners in their lives.
